Funding rounds are stages where startups raise money from investors to grow their business. In the crypto world, this can include ICOs (Initial Coin Offerings), where a project sells tokens to the public to raise funds, IEOs (Initial Exchange Offerings), which are similar but conducted through a cryptocurrency exchange, and private rounds where venture capitalists invest in the project. Each round of funding helps the startup develop its product, expand its team, and reach new milestones.
